Jose Canseco Won't Play in Mexico After Admitting to Taking Banned Substance

Jose Canseco's attempt at a Kenny Powers-style comeback was cut short when, according to ESPN Deportes, the former MLB-slugger-turned-steroid-crusader admitted to officials in the Mexican Baseball League that he had ingested a banned substance for which he did not have a proper prescription.

Canseco had auditioned for the Quintana Roo Tigers, but was forced out of the league after refusing to submit to a drug test, which Plinio Escalante, the president of the Mexican league, says would've revealed Canseco's use of testosterone.

The six-time All-Star, two-time World Series champion and 1988 AL MVP hasn't set foot in a major-league game since 2001, when he was a member of the Chicago White Sox. The Mexican league is loosely associated with MLB as a Triple-A minor league, though none of its clubs are directly affiliated with big-league organizations.

Canseco, who's best known for his days as a member of the "Bash Brothers" next to Mark McGwire with the Oakland A's, played for seven teams during his 17-year major-league career. He hit 462 home runs and drove in 1,407 runs along the way.

He's since become a lightning rod of controversy within the sport for publishing a book in which he outed a number of his own peers for their alleged use of performance-enhancing drugs.
